PLEASE HELP WITH GEOMETRY!! WILL GIVE BRAIN!!!

xenn [34]

Answer:

1,726 cm

Step-by-step explanation:

it boils down to this equation:

2(19×29)+2(19×6.4)+2(29×6.5)

bc if you look closely, it's just each side twice (hope that makes sense)

then you work down from there

2(551)+2(123.5)+2(188.5)

1,102+259+337

1,726

Mai and Tyler work on the equation 2/5b+1=-11 together. Mais soulution is b=-25 and Tyler’s is b=-28. Here is their work. Do you

Anika [276]

Answer:

No I don't agree with their solution; both their answers are wrong.

Correct answer is $b=-30$ .

Step-by-step explanation:

Given:

$\frac{2}{5}b+1=-11$

Now given:

According to Mai $b = -25$ and According to Tyler $b = -28$

Now we need to find which of them is correct.

So we will solve the given equation we get;

$\frac{2}{5}b+1=-11$

Subtracting both side by 1 we get;

$\frac{2}{5}b+1-1=-11-1\\\\\frac{2}{5}b =-12$

Now Multiplying both side $\frac{5}{2}$ we get;

$\frac{2}{5}b\times\frac{5}{2}= -12 \times \frac{5}{2}\\\\b=-6\times 5\\\\b=-30$

Hence both of them are incorrect, correct answer is $b=-30$ .
